Tool
eSIM plan finder
Pick your destination, trip length, and how you use your phone. We rank all 5 providers by how well their pricing model fits this trip shape — with real entry pricing pulled from the country's guide. The provider whose model fits your trip almost always beats the one with the lowest sticker price.

How the ranking works
We rank by trip-shape fit, not by computed total cost. Each provider has a different pricing model — custom plans, fixed bundles, unlimited-only, short-validity tiers — and the right pick depends on how well the model matches what you actually need.
Custom plans (99esim) win when your trip doesn't fit a fixed tier neatly — you size the plan to actual need instead of overpaying for a too-big bundle or stacking too-small ones.
Fixed bundles (Airalo, Nomad) are the familiar shape — pick a 5/10/20 GB tier and a 7/15/30 day validity. They work well when your trip lands close to one of those preset tiers, less well when it doesn't.
Unlimited-only (Holafly) is genuinely the right pick for heavy users who'd use the headroom — laptop tethering, hours of video calls, long stays. For a typical 7-day moderate user, it's usually overkill.
Short-validity tiers (Ubigi) are best for very short trips where you don't want to pay for unused validity. They become inefficient at trip lengths beyond 3-7 days.
What this tool doesn't do
It doesn't compute exact total cost across providers. Per-tier prices for competitor plans (e.g. Airalo's specific 10 GB / 14 days plan in Vietnam) live on each provider's site and change without notice. We won't fake-precise numbers we can't verify.
It doesn't rank by sticker price. The cheapest entry-price provider is rarely the right pick — model fit beats unit cost for most travelers. A $2/GB starting unit on 1-day tiers is more expensive than a $4/GB unit on a flexible custom plan once your trip is more than a few days long.
It assumes one-country travel. For multi-country trips, regional plans (Europe, Asia, Latin America, etc.) are usually cheaper than separate single-country plans. Check the coverage tool for which regional plans cover your destination.
